Short answer: the Kali Audio LP-6 V2. It ranks #25 of 68 powered bookshelf speakers by sound quality (rated 4.4/5) at $398 and is still sold new; the JBL 4329P ranks #45 (rated 4.1/5) and is discontinued, so it is only an option used.
On the Kali Audio LP-6 V2 side: Outstandingly neutral active monitor for the money, with no audible amplifier hiss in Erin’s listening and excellent horizontal directivity from the contoured waveguide. Set against that: A vertical directivity disturbance around 1.5-2kHz makes ear height important; desk or console reflections and ceiling bounce can expose the crossover lobing, so absorption may help.
The case for the JBL 4329P: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement. The tradeoff: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC.
Buy the Kali Audio LP-6 V2. It is rated higher for sound quality and still sold new, while the JBL 4329P is discontinued.

Kali Audio LP-6 V2: $398 per pair Amazon B&H Photo Video eBay
Older model: the Kali Audio LP-6 (ranked lower, rated 4.3/5).
Pros: Erin’s measurements give a 7.48 ideal-subwoofer score and 42.5Hz -3dB bass extension, a strong combination for an affordable nearfield monitor. The waveguide and placement switches help with practical setup, and the second generation improves close-range noise behavior. Measured bass extension of 42Hz (-3dB).
Cons: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness. Vertical crossover behavior makes ear-height placement important, and compression limits loud bass playback. Its good tonal score is not evidence of the output capability of a much larger monitor.

JBL 4329P: $4,500 per pair Discontinued eBay
Pros: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. Integrated amplification and streaming make it convenient for a full-range living-room system, and its larger format is useful when scale matters. Measured bass extension of 31Hz (-3dB), with a measured sensitivity of 102.2dB.
Cons: The measured 4.5dB response span from 300Hz to 5kHz includes a notable midrange dip, so it is not as neutral as its size and price might suggest. Its 6.72 ideal-subwoofer score trails the 4305P. There is no HDMI connection for the simplest TV hookup. Discontinued.
